Method for cooling battery of electric vehicle

Abstract

Abstract PURPOSE:To prevent the rise in the temperature of a battery for an electric vehicle, by supplying a liquid coolant to a coolant evaporation layer, and sending a natural convection wind or a fan wind to promote the evaporation of the liquid coolant. CONSTITUTION:A coolant evaporation layer 2 is made of a porous material. A coolant gutter 3 surrounds the bottom of the outside wall of the body of a battery or an electrolyte vessel 1. The bottom of the coolant evaporation layer 2 is located in the coolant gutter 3 to such up a coolant by a capillary action. A liquid coolant filled in a liquid coolant vessel 4 is supplied to the coolant gutter 3 through a conduit 4'. As the liquid coolant is being supplied to the battery body or the electrolyte vessel 1, a natural convention wind caused by the movement of a vehicle or a fan wind is applied to the peripheral portion of the battery body or the electrolyte vessel to promote the evaporation of the liquid coolant. Latent heat is thus absorbed to cool the the outside wall of the battery body or the electrolyte vessel 1.
